You will have certainly fogged the first few feet. If you are real lucky, maybe just the outer edges further in on the roll. Try taking a few inches from the center of the roll and developing it to see if it has fogged. Bin the first few feet from the outside and try developing another snip.
Wot he said.
Warning!! Handling a Hasselblad can be harmful to your financial well being!
Nothing beats a great piece of glass!
I leave the digital work for the urologists and proctologists.
Another person had the same problem recently and he only destroyed the first 5' or so. It is always wound so tight there is little damage. Might be difficult to remove the last few ft from the inside of the roll. The best is just remove 10' or so then test. Here is a photo of the outcome of the damaged roll as you can see very little was destroyed. The edges are toast but make sure you don't use the first 20' for anything important. After that you should be fine.
I would be careful about handling Retro 80s. I have only bought it in 35mm cassettes before, and not bulk, but it seems to be prone to fogging. I now take the cassettes from their containers, and load/unload the camera in a changing bag. I don't know if others have had similar fogging issues with this film.
I've used the Retro 80s in my 2.25 pinhole and gotten nice results. In case you didn't know, this film is extended red sensitivity. It falls off sharply at 720nm though so it's fairly slow. Could be the fogging was IR related.
